AI Technical Summary
The bearings of the vibratory box of the floor slab forming machine are not lubricated in time, resulting in irregular and untimely lubrication. In addition, the bearing temperature is too high during operation, which affects the service life.
A bearing lubrication structure for a vibratory box of a floor slab forming machine is designed. It adopts a combination of open oil passages and guide holes to achieve real-time synchronous lubrication of lubricating oil. The eccentric block assembly driven by the transmission shaft throws the lubricating oil into the open oil passages and into the bearing hole to achieve circulating lubrication and cooling.
This ensures timely lubrication, extends bearing life, reduces bearing temperature, and improves equipment operational stability.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of floor slab forming machines, and specifically relates to a bearing lubrication structure for a vibratory box of a floor slab forming machine. Background Technology
[0002] The main purpose of floor slab forming machines is to produce various types of floor slabs, which are widely used in residential, commercial, industrial and public buildings and other fields.
[0003] The vibratory box is one of the important components in the floor slab forming machine. The vibratory box generally includes a box body and a vibratory assembly. The vibratory assembly includes a drive shaft and an eccentric block assembly. The drive shaft is rotatably connected to the box body through bearings, and the bearings are assembled in bearing holes on the box body. The bearings generally need to be lubricated with grease regularly. Currently, this is usually done manually, which results in problems with irregular and untimely lubrication. In other words, it cannot achieve timely lubrication. In addition, since grease is generally used, the bearing temperature can easily become too high during the operation of the floor slab forming machine, which will affect the bearing's service life. Utility Model Content
[0004] This utility model provides a bearing lubrication structure for a vibratory box of a floor slab forming machine, which can solve the problems pointed out in the background art.
[0005] A bearing lubrication structure for a vibratory box of a floor slab forming machine includes a vibratory box body, the vibratory box body including a housing and a vibration component; the vibration component including a drive shaft and an eccentric block assembly; the housing is provided with lubricating oil; the upper part of the housing is provided with an open oil passage; the open oil passage is provided with a guide hole; the guide hole is used for communication between the open oil passage and the bearing hole; the open oil passage is set higher than the bearing hole.
[0006] Preferably, the open oil passage is an oil trough located on the upper inner wall of the housing.
[0007] Preferably, the upper inner wall of the box is provided with oil grooves on all four sides, and the oil grooves are continuously connected.
[0008] Beneficial effects: This utility model provides a bearing lubrication structure for a vibratory box of a floor slab forming machine, which can achieve real-time lubrication of the bearing as long as the vibratory box is working, thereby achieving timely lubrication and also helping to cool down the bearing, thus improving the service life of the bearing.

[0014] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0015] Example 1:
[0016] like Figure 1-3 As shown in the figure, this utility model provides a bearing lubrication structure for a vibratory box of a floor slab forming machine, including a vibratory box body, which includes a housing 1 and a vibration assembly; the vibration assembly includes a drive shaft 2 and an eccentric block assembly 3; the housing 1 is filled with lubricating oil, the depth of which should be lower than the lowest point of the bearing hole 6 to prevent overflow, and an oil seal is provided on the outermost side of the bearing to prevent overflow; the upper part of the housing 1 is provided with an open oil passage 4, and the open oil passage 4 is provided with a guide hole 5, which is used for communication between the open oil passage 4 and the bearing hole 6; the open oil passage 4 is higher than the bearing hole 6. Hole 6 is provided, and the open oil passage 4 has an open upper opening. There is a certain distance between the open upper opening of the open oil passage 4 and the upper cover of the box 1 to facilitate the entry of lubricating oil. The upper cover of the box 1 is closed, and a sealing strip is used to seal the upper cover and the box 1 to prevent oil leakage. When the vibration box is working, the drive shaft 2 drives the eccentric block assembly 3 to rotate. The eccentric block assembly 3 will throw part of the lubricating oil in the box 1 to the open oil passage 4. Part of the lubricating oil will enter the open oil passage 4 through the open upper opening, and finally enter the bearing hole 6 through the guide hole 5 under the action of gravity, so as to lubricate the bearing in real time and realize circulating lubrication.
[0017] Specifically, the open oil channel 4 is an oil groove set on the upper inner wall of the box body 1. The oil groove can be connected by welding. The upper inner wall of the box body 1 is provided with oil grooves all around, and the oil grooves are continuously connected. The guide hole 5 is an oblique drilled hole.
[0018] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
